Syringe Filter

Introduction

Microlab Scientific BioFil™ Syringe Filters design with a layer of prefilter. Ideal for filtering solutions with a high load of particulate matter. All the Syringe filters are well packed, with competitive price filters. The membranes range from Nylon, CA, MCE, PES, PTFE, PVDF, GF, Regenerated Cellulose(RC) to PP, which are supplied in 13mm and 25mm no virgin medical PP housings. 

 

Test Method

Agilent Technologies 1200, Column: C18 UV = 254 nm Mob.phase:MeOH/H2O:20:80, Temperature: 25°C, Flow rate:0.8ml/min, sample:2mg/ml Bergenin(in Methanol)

 

Why to use a syringe filter?

 

Why choose Biofil™ Syringe Filter? ?

1. HPLC certification which guarantees the filters will not produce extraneous peaks in the UV range.
2. 100% integrity tested with higher burst strength ratings assuring they will perform consistently.
3. Suitable for solutions with a high load of particulate matter.
4. Larger handling capacity.
5. Long Life Time.

 

How to select your sample preparation device?

Step 1: Choose the suitable membrane filtration medium Characteristics of samples

Solutions	Recommended
Solvent Mixtures	Nylon, Hydrophilic PTFE,
Tissue culture Media, Buffers, Protein Analysis/ Biological Samples	CA, PES, MCE, Hydrophilic PVDF
High Particulate Loads	PP,GF, Filter with pre-filter
Aggressive or Pure Organic Solvents	Hydrophobic PTFE, PVDF

Step2: choose the suitable diameter

Volume of samples	Recommend
<10ml	13mm
<100ml	25mm

 

Step 3: Choose the suitable pore size based on the nature of your sample

• Removal of high particulate matter with a pre filter is critical before any drug, toxic, or dirty environmental sample is filtered to ensure the highest syringe filter membrane performance.
• Generally, 0.45 μm porosity filters are used to remove particulates from samples and mobile phase solutions. For Sterile-filtration, a 0.20 μm porosity filter can be used.
